PHILIP E. NEWSOM, OF NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent N 0. 736,538, dated August18, 1903.

Application filed February 20, 1903. Serial No. 144,225. (No model.)

To all whom it may concern.-

Be it known that I, PHILIP E. NEWsoM, residingat the borough ofBrooklyn, city of New York, in the county of Kings and State ofNew York,have invented certain new and useful Improvements in Automatic Apparatusfor Extinguishing Lamps, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention relates to apparatus for auto-v matically extinguishing a1ight,and especially an oil-lamp, at a predetermined time, and has forits object to provide a simple, inexpensive, and easily-operated deviceof this character. Other objects will appear from the hereinafterdescription.

The invention consists in certain novel fea tures of constructions andcombinations of parts, all as hereinafter fully described and claimed.

Referring now to the drawings which form a part of this specification,and in which I have illustrated my device as applied to an oil-lamp,Figure 1 is a rear elevation of the apparatus. Fig. 2 is a detail Viewof certain parts thereof. Fig. 3 is another detail View with certainparts in different position from that shown in Fig. 2. Fig. 4 is a frontview of certain parts shown in Figs. 2 and3. Fig. 5 is an illustrationof the extinguisher as ap plied to the lamp-burner. Fig. 6 is a frontView of the device shown in Fig. 1, and Fig. 7 illustrates amodification. 7

Referring now to the drawings, in which the same reference-lettersindicate the same parts in the different views, A represents a clock, bythe mechanism of which the extinguisher is released.

B represents a lamp, and 0 represents the burner of the lamp.

The clock consists of the usual mechanism by which the extinguisher,hereinafter to be described, carried by the lamp-burner, is released.

D is the front frame, and E is the rear frame, of the clock mechanism.

F is a shaft mounted in the frame, having on the rear end thereof a keyf, by which it maybe turned. To the front end of this shaft is attachedthe hand Gr, shown on the face of the clock, adapted to be set at anhour at which the light is to be extinguished.

H is a disk also secured to the shaft inside of the face of the clockand having connected thereto a finger or log h.

J is a gear-wheel loosely sleevedon the shaft F inside of the disk H andis driven by the mainspring K of the clock mechanism through the seriesof gear wheels and pinions K K K &c.

J is a ring or band connected to the gear J, having a recess J in theouter edge thereof, which has an inclined face J The internal diameterof this band is such that it will fit over the disk H when the finger hof the disk is in the recess J of the band.

J is a sleeve secured to the inside face of the gear J and against whichthe spring L rests. This spring is attached to the frame D and has thefree end thereof inturned into a finger, as shown at L. The spring restsagainst the sleeve J" and tends to force the gear toward the forward endof the shaft E. The finger h, bearing against the edge of the band Jexcept when the notch or recess J is opposite the finger h, keeps thespring pressed in.

M is a rock-shaft pivoted between the frames D and E. m is an armconnected near the front end of this shaft in such position that itcomes in contact with the finger of the spring when the finger is pushedin. N is an arm connected near the other end of the rockshaft M. Thefree end of this arm rests in a notch O of the rear frame E of the clockmechanism.

C is the bottom plate of the burner, and O is the wick-tube securedthereto.

P is the extinguisher pivoted to the burnerplate 0.

Q is a rod, one end of which is connected to the extinguisher at q, andthe other end is bent or curved, as indicated by q, in such manner thatthe rod can be held by the arm N, heretofore described. R is acoil-spring surrounding this rod, one end of the spring being connectedto the burner-plate G and the other secured to the rod, so that it tendsto move the rod upwardly and throw the ex tinguisher over the top of thewick-tube.

The apparatus operates as follows: Suppose it is decided to extinguishthe light at nine oclock, for example. The shaft F is turned by the keyfuntil the small hand on the face of the clock (shown in Fig. 6) pointsto 9. When in this position the finger h of the disk H will be on theouter edge of the collar J, and the gear J will be moved inwardly.pressing in the spring L, so that the finger L thereof will be in thepath of movement of the arm m, so that the shaft M cannot be rocked. Inthis position the arm N will be seated in the notch O of the rearframeE, as shown in Fig. 1 of the drawings. The

rod Q is now pulled down, and the bent end q catches under the arm N,whereby the rod is held down against the tension of thespring R, and theextinguisher P is pulled down from over the lamp-wick, so that the lightwill burn in the usual manner. The parts will stay in this positionuntil the hourof nine arrives. At this time the gear J will have beenrotated by the clock mechanism, and the recess J in the edge thereofwill come opposite the finger h, when the spring L will force the gear Jout to the position shown in Fig. 3, with the finger h of the disk H inthe recess J of the ring J. The springfinger L is now out of engagementwith the arm N, and the lever may now be rocked. The spring Rwill thenpull on the rod Q, and the arm Nwill be raised out of its seat 0,permitting the rod to be released and pulled up, whereupon theextinguisher P will be thrown over the upper end of the wick-tube andextinguish the light. To reset the device, the shaft F is again turnedby the key fto the right, whereupon the finger will ride out of therecess J on the incline surface J of the recess, when the gear willbeforced inwardly, moving with it the spring L, so that the finger Lthereof will again come in contact with the arm M to hold the arm N inits seat 0, so that the rod can be again held down by the curvedlowerend q thereof hooking over the arm and holding the extinguisher awayfrom the light against the tension of the spring R.

In the modification that I have illustrated in Fig. 7 the clockmechanism is placed in one room and the lamp B in another, and the rod Qis bent, so that it will pass from one room to the other through anopening, as shown at S. The spring R in this case has its upper endsecured to a bracket O and the that I may use the same device forextinguishing electric and other lights.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a device for extinguishing alight, an extinguisher connected tothe light, a clock, an arm, devices for controlling the arm by the clockmechanism, means for releasing the arm,and means between the arm and theextinguisher whereby, upon the release of the arm, the extinguisher willbe operated to extinguish the light.

3. In a device of the class described, a burner, an extinguisher forsaid burner, a rod having one end thereof connected to the extinguisher,a spring connected to the rod and adapted to move the rod to throw theextinguisher over a light, a clock mechanism, an arm carried thereby andadapted to engage the rod to hold the rod against the tension of thespring, the said rod adapted to be released when the clock mechanismreaches a certain point, as and for the purpose set forth. 1

4. In an apparatus of the class described, a clock mechanism, a shaftmounted therein, said shaft carrying a disk on one end, said disk havina fin er connected thereto a ear loosely mounted on the shaft andadapted to be driven by the clock mechanism, means on the gear adaptedto be controlled by the finger of the disk, a spring adapted to becontrolled shaft,a burner,an extinguisher for the burner,
